In a bowl with a lid, whisk together honey, bourbon, soy, Worcestershire, garlic, salt, and pepper. Add steak cubes, seal, shake, and refrigerate for 2 hours.
Heat your cast iron pan on medium-high heat. When it's hot add vegetable oil and butter. Once the oil and butter ripple, add steak.
You probably need to cook it in a couple of batches. You don't want to crowd the pan so that the steak sear and don't steam.
Cook until seared on all sides. Remove from pan. Pour pan drippings over the top.
